/**
 * Review Model Config Tests (#1849)
 *
 * Verifies the review.models.<cli> dynamic config key pattern:
 *   - isValidConfigKey accepts review.models.<cli-name>
 *   - validateKnownConfigKeyPath suggests review.models.<cli-name> for review.model
 *   - End-to-end round-trip via config-set / config-get for both model IDs and null
